  Revert "[llvm][cmake] Make `install_symlink` workflow work with absolute install dirs"

`ExtendPath` needs to be moved from internal to external CMake if it is
to be used to `AddLLVM`. See, for example, the failure in
https://lab.llvm.org/buildbot#builders/61/builds/29940

This reverts commit 5acd376438a53747c84e38c8b69fc74a270da680.
